Purpose: This year 2020 marks the 50th anniversary of the founding of the Korean Society of Nursing Science (KSNS). This study wasaimed to explore development of caring and describe the 50 years of history of KSNS within the sociocultural context of Korea regardingacademic footsteps, meanings, and implications for the future. Methods: This study used a historical research methodology using a literaturereview and bibliometric analysis. Relevant literature was reviewed and the published abstracts in the Journal of Korean Academy ofNursing (JKAN) were analyzed using VOSviewer. Results: Birth control and family planning in the 1970s was the main research topic. In the1980s, the development of nursing concepts, theories, and philosophies was the mission of KSNS to extend the disciplinary boundary. In the1990s, the progress of KSNS to become one of the woman-dominant healthcare professionals was the mission in the given period. Expandingthe frontiers of KSNS to the extent of global standards was the undertaking of the nursing scholars in the 2000s. Lastly, in the 2010s,the quality and quantity improvement of KSNS and JKAN is expected to make our future even prosperous. The map visualization of the 50years of research accumulation showed the comparable opposition of quantitative vs. qualitative research methodologies, equation modeling,and instrument development. Conclusion These clusters of research demonstrates the efforts to make nursing evidence by Koreannursing scholars for the last five decades. The growth in the slope of KSNS and outcomes of JKAN are to carry on to an unimaginable extentin the future.

Hereditary angioedema is a disease of congenital deficiency or functional defect in the C1 esterase inhibitor (C1-INH) consequent to mutation in the SERPING1 gene, which encodes C1-INH. This disease manifests as recurrent, non-pitting, non-pruritic subcutaneous, or submucosal edema as well as an erythematous rash in some cases. These symptoms result from the uncontrolled localized production of bradykinin. The most commonly affected sites are the extremities, face, gastrointestinal tract, and respiratory system. When the respiratory system is affected by hereditary angioedema, swelling of the airway can restrict breathing and lead to life-threatening obstruction. Herein, we report a case of a 24-year-old woman with type 2 hereditary angioedema who presented with recurrent episodic abdominal pain and swelling of the extremities. She had no family history of angioedema. Although her C4 level was markedly decreased (3.40 mg/dL; normal range: 10-40 mg/dL), she presented with a very high C1-INH level (81.0 mg/dL; normal range: 21.0-39.0 mg/dL) and abnormally low C1-INH activity (less than 25%; normal range: 70%-130%). The SERPING1 gene mutation was confirmed in this patient. She was treated with prophylactic tranexamic acid, as needed, and subsequently reported fewer and less severe episodes. To our knowledge, this is the first reported case of type 2 hereditary angioedema in Korea that was consequent to SERPING1 mutation and involved a significantly elevated level of C1-INH as well as a low level of C1-INH activity.

This study aimed to investigate the anti-inflammatory and wound healing effects of Corchorus olitorius cultivated in smart farms. In current study, component analysis, cell viability, anti-inflammatory activity and wound healing assay were conducted with 70% ethanol extracts of C. olitorius (ECS) grown in smart farms.Chlorogenic acid that is an indicator for C. olitorius was analyzed by high performance liquid chromatography (HPLC) and, as a result, ECS had 23.52 mg/g of chlorogenic acid. The expression of inflammatory mediators such as nitric oxide (NO) and pro-inflammatory cytokines was measured using griess reaction, enzyme-linked immunosorbent assay (ELISA) and reverse transcription polymerase chain reaction (RT-PCR). The results showed that NO, TNF-α, and IL-6 production levels were inhibited by ECS at a dose dependent manner in LPSstimulated RAW 264.7 cells. Additionally, the expression of mRNA was also suppressed by ECS at a dose dependent manner in LPS-stimulated RAW 264.7 cells. To confirm the effect of wound healing of ECS, cell proliferation and migration were examined in fibroblasts and keratinocytes. Consequently, it was confirmed that ECS showed the wound healing effect by promoting cell migration in fibroblasts and keratinocytes. These results suggested that ECS can prevent chronic wound by regulating chronic inflammation with anti-inflammatory activities and can be a new candidate material for treatment of skin wound.

A duodenal web is an incomplete diaphragm of the duodenal lumen that causes a partial or (intermittent) complete obstruction. The size of a duodenal web’s aperture determines the degree of obstruction, age at presentation, and radiologic findings. We report a case of duodenal web incidentally diagnosed in a 14-month-old boy who presented to the hospital after ingesting a foreign body. We provide a comprehensive report of multiple studies through abdominal radiograph, upper gastrointestinal study, endoscopy, and surgical findings. We emphasize that the duodenum should be considered as the location of the obstruction when infants exhibit delayed discharge or dynamic positioning of a foreign body in a radiologic examination.

PURPOSE: The aim of this study was to evaluate whether infants with rhinovirus (RV) infection-induced wheezing and those with respiratory syncytial virus (RSV) infection-induced wheezing have different cytokine profiles in the acute stage. METHODS: Of the infants with lower respiratory tract infection (LRTI) between September 2011 and May 2012, 88 were confirmed using reverse transcription polymerase chain reaction and hospitalized. Systemic interferon-gamma (IFN-γ), interleukin (IL)-2, IL-12, IL-4, IL-5, IL-13, and Treg-type cytokine (IL-10) responses were examined with multiplex assay using acute phase serum samples. RESULTS: Of the 88 patients, 38 had an RV infection (RV group) and 50 had an RSV infection (RSV group). In the RV group, the IFN-γ and IL-10 concentrations were higher in the patients with than in the patients without wheezing (P=0.022 and P=0.007, respectively). In the RSV group, the differences in IFN-γ and IL-10 concentrations did not reach statistical significance between the patients with and the patients without wheezing (P=0.105 and P=0.965, respectively). The IFN-γ and IL-10 concentrations were not significantly different between the RV group with wheezing and the RSV group with wheezing (P=0.155 and P=0.801, respectively), in contrast to the significant difference between the RV group without wheezing and the RSV group without wheezing (P=0.019 and P=0.035, respectively). CONCLUSION: In comparison with RSV-induced LRTI, RV-induced LRTI combined with wheezing showed similar IFN-γ and IL-10 levels, which may have an important regulatory function.

Endometriosis, defined as growth of endometrial stroma and glands outside the uterine cavity, is a chronic and recurrent disease that affects patients' quality of life. Ectopic endometrial tissue can proliferate at any location in the body, but the pelvic organs and peritoneum are the most frequent implantation sites. Among extrapelvic endometriosis, inguinal endometriosis is a very rare gynecologic condition usually associated with previous pelvic surgery. Endometriosis should be preoperatively distinguished from other inguinal masses using computed tomography, magnetic resonance imaging, or ultrasonography. Here, we report a case of right inguinal endometriosis in a patient with no previous history of gynecologic surgery; in addition, we have provided a brief review of relevant literature.

PURPOSE: The purpose of this study was to compare the validity of Onen's alternative grading system (AGS) with that of the APDRP and SFU grading systems in patients with isolated and complicated congenital hydronephrosis. METHODS: We retrospectively reviewed the medical records of 153 patients (204 renal units) diagnosed with congenital hydronephrosis between January 2002 and December 2011. We classified patients into 2 groups; isolated or complicated hydronephrosis. All renal units were graded according to anterior-posterior diameter of renal pelvis (APDRP), Society for Fetus Urology (SFU) and Onen's grading systems. We analyzed the prognosis of hydronephrosis, according to each grading system, at 2 years of age. RESULTS: There were 152 renal units with isolated hydronephrosis and 52 renal units with complicated hydronephrosis. The isolated hydronephrosis group had a lower grade according to Onen's AGS, and showed more frequent spontaneous remission by 2 years of age. There was more frequent obstruction (P=0.000) and surgical treatment (P=0.000) of units with high-grade hydronephrosis according to Onen's AGS. In the complicated hydronephrosis group the frequencies of spontaneous remission (P=0.015) and renal dysfunction (P=0.013) were significantly higher than those in high-grade hydronephrosis, as indicated by Onen's AGS. There were no significant differences in clinical outcomes among the highest grade groups, according to the 3 systems, in either isolated or complicated hydronephrosis. CONCLUSION: Onen's AGS reflects the prognosis of hydronephrosis as well as other grading systems in those with isolated hydronephrosis. It was better predictor of renal dysfunction in those with complicated hydronephrosis. However, Onen's AGS was not superior to the other grading systems in terms of predicting prognosis, especially in high-grade hydronephrosis.

Background: Mast cells are skin immune sentinels located in the upper dermis, where wheal formation and sensory nerve stimulation take place. Skin inflammation is occasionally accompanied by mast cell-driven responses with wheals, angioedema, or both. Immunoglobulin E (IgE) antibodies are regarded as typical stimuli to drive mast cell activation. However, various causative factors, including microbial infections, can drive IgE-independent mast cell response. When infected, the innate immunity orchestrates an immune response by activating receptor signaling via Toll-like receptors (TLRs). Objective: In this study, we determined the effect of TLR7 stimulation on mast cells to investigate the possible mechanism of IgE-independent inflammatory response. Methods: Human mast cell (HMC) line, HMC-1 cells were treated with TLR7 agonist and the morphologic alteration was observed in transmission electron microscopy. Further, TLR7 agonist treated HMC-1 cells were conducted to RNA sequencing to compare transcriptomic features. Results: HMC-1 cells treated with TLR7 agonist reveals increase of intracellular vesicles, lipid droplets, and ribosomes. Also, genes involved in pro-inflammatory responses such as angiogenesis are highly expressed, and Il12rb2 was the most highly upregulated gene. Conclusion Our data suggest that TLR7 signaling on mast cells might be a potential therapeutic target for mast cell-driven, IgE-independent skin inflammation.

The cellular entry of severe respiratory syndrome coronavirus-2 (SARS-CoV-2) is mediated by interaction with the human angiotensin-converting enzyme 2 (ACE2), a receptor that is expressed on both lung and intestinal epithelial cells. We performed a quantitative proteomic analysis to investigate the expression of possible receptors for SARS-CoV-2 in the intestinal mucosa of 23 patients with chronic colitis. ACE2 expression was low and remained unaltered in the gut of patients with ulcerative colitis (UC), Crohn’s disease (CD), intestinal Behćet’s disease (BD), and intestinal tuberculosis (TB), when compared with that of healthy individuals. Additionally, the expression levels of some probable co-receptors, including dipeptidyl peptidase 4 (DPP4), aminopeptidase N (AMPN), and glutamyl aminopeptidase (AMPE), were unchanged in the affected UC, CD, intestinal BD, and intestinal TB colon mucosa samples. In conclusion, gut inflammation associated with chronic colitis does not mediate a further increase in the cellular entry of SARS-CoV-2.
